Oscar G. Mayer, retired chairman of the Wisconsin-based meat processing company that bears his name, has died at the age of 95.

Mayer’s wife, Geraldine, said he died of old age Monday at a Hospice Care in Fitchburg.

He was the third “Oscar” in the Mayer family and founded Oscar Mayer Foods, which was once the largest private employer in Madison. His grandfather, Oscar F. Mayer, died in 1955 and his father, Oscar G. Mayer Sr., died in 1965.

Mayer retired as chairman of the board in 1977 at age 62 soon after the company recorded its first $1 billion year. The company was later sold to General Foods and is now a business unit of Kraft.

Mayer’s first wife, Rosalie, died in 1998. He married Geraldine Fitzpatrick in 1999.
